What You'll Do

• Lead the design and implementation of multi-platform editor extensions that bring GitLab Duo into developers’ daily workflows, from discovery through rollout and iteration.
• Design, build, and operate TypeScript and Node.js services for the GitLab Duo CLI, ensuring strong reliability, observability, and performance.
• Develop and enhance our JetBrains IDE plugin in Kotlin using the IntelliJ Platform SDK, guiding architectural decisions to maintain performance and maintainability.
• Implement and evolve features in our GitLab Language Server to deliver consistent AI-assisted workflows across editors and platforms.
• Build modern, accessible UI components using Vue 3, shadcn-style component libraries, and Tailwind-based theming for our editor experiences.
• Shape our multi-platform architecture, identify and reduce technical debt, and drive improvements to scalability and developer experience.
• Collaborate with product, design, and engineers across AI Engineering to align technical decisions with our broader multi-platform strategy and deliver iterative improvements.
• Champion product quality, security, performance, and developer experience through high-quality reviews, mentorship, and shared standards across TypeScript and Kotlin codebases.

Requirements

• Strong proficiency with TypeScript across frontend and backend, including building and operating production Node.js services.
• Experience building developer tooling, such as command-line applications and rich interactive terminal experiences.
• Experience with IDE extension ecosystems (for example, JetBrains IDEs), including plugin architecture, lifecycle, and development workflows.
• Working knowledge of Kotlin (or modern Java) and interest in contributing to Kotlin-based JetBrains plugins using the IntelliJ Platform SDK.
• Understanding of the Language Server Protocol (LSP) and practical experience with language servers and editor integrations.
• A track record of owning large technical problems end to end, making sound architectural trade-offs, and mentoring other engineers through code reviews and guidance.
• Comfort working in a fully remote, largely asynchronous environment, with clear written and spoken English communication and alignment with GitLab’s values and inclusive culture.

Nice to Have

• Experience with Vue.js and Tailwind CSS.
• Familiarity with AI technologies and their application in software development.
• Previous experience in a remote-first company.
